Specification of Letters Patent.

Patented June 9, 1914:.

Application filed September 13, 1912. Serial No. 720,126.

To all whom it may concern Be it known that I, ALBERT V. PFLAUMM, a citizen of the United States of America, and a resident of the city of Tonasket, in the county of Okanogan and State of ashington, have invented certain new and useful Improvements in Water Elevating and Impelling Apparatus, of which the following is a specification.

My invention has for one of its objects to provide a novel construction of the above type wherein the plunger is controlled to have its direction of movement automatically reversed.

A further object is to provide mechanism whereby the downward or active movement of the plunger will be governed to overcome undue increase in speed thereof.

Further the invention consists in the provision of a generally simplified and improved construction.

Referring to the accompanying drawing wherein like numerals of reference indicate like parts throughout: Figure 1 is a fragmentary section ofan apparatus constructed in accordance with my invention, arranged to receive fluid from a fiume. Fig. 2 is a top plan thereof, parts being broken away. Fig. 3 is a fragmentary sectional view illustrating more particularly the drum on the crank shaft of the engine, constituting a part of the starting mechanism. Fig. 1 is a fragmentary vertical cross-sectional view of the apparatus, illustrating more particularly the valve in the fluid delivery pipe and the driving connection between the latter and the elevating drum for the plunger. Fig. 5 is a. vertical cross-sectional view of the apparatus taken through Fig. 2. Fig. 6 is a vertical section taken on line 66 of Fig. 3, and Fig. 7 is a diagrammatical showing of an alternative drive mechanism for ele vating the plunger.

Referring to the drawings by numerals of reference, 1 indicates a chamber provided in its lower portion with an outlet with which communicates a delivery pipe 2, and 3 indicates a weight plunger which is adapted to lower by gravity and expel the underlying water through pipe 2, in a manner hereinafter more fully set forth.

Plunger 3 is formed to permit ofthe passage of water therethrough, the same. as now considered, being formed with four ports 1 controlled by valves 5, pivoted at 5 its upper end secured to a drum 10, which drum is fixed to a shaft 11 to which power is applied from a drive shaft 12 by a sprocket chain 13 passing over sprocket wheels 14 and 15 of the shafts 11 and 12 respectively.

Shaft 11 has one end portion externally screw threaded and engaged in a threaded aperture of an upright 16 of a base 17 of the supporting frame. The opposite end portion of shaft 11 is slidably fitted in a second upright 16, and to this last named end portion of shaft 11, sprocket wheel 1 1 is splined so that it will turn with the shaft but not shift therewith during its axial movement.

Reference numeral 18 indicates an angular finger on upright 16 which engages in a peripheral groove in the hub of sprocket wheel 1% and thereby holds the latter.

With the parts arranged as shown in Fig. 1, plunger 3 will lower by gravity and expel the under-lying water through pipe 2. In this connection however it will be observed that during this downward movement of plunger 3, water from the fiume, as 19, is constantly admitted through the port 20 of chamber 1 and therefore has its weight applied to plunger 3, and thereby effect a gradually increasing movement of the latter. To prevent this increase reaching undesirable proportions, I provide in delivery pipe 2 a valve 21, this being a slide valve which is guided in a housing 22 for movement into and out of pipe 2. This adjustment of valve 21 is effected automatically through a rod 23 having one end portion threaded in valve 21 and its opposite end portion telescoped by and splined in the externally threaded end portion of shaft 11, as more clearly shown in Fig. 4. By slidably connecting rod 23 with shaft 11 the screw threads on these elements can be of relatively different, pitch, thereby enabling the shaft being adjusted a greater distance than the valve. For elevating plunger 3 I provide a motor which, in the construction shown in Figs. 1 to 6 inclusive, consists of an explosive engine 24.

Reference numeral 25 indicates an electrical circuit in which the sparking device, conveniently shown as a spark plug 26 is included. For opening and closing circuit 25, I provide a switch 26 pivoted on a stand 27. The engine start-ing mechanism includes a drum 28 loosely mounted on one end portion of the engine crank shaft 29 and connected with a spring 30, fixed at one end to a stand 31.

Reference numerals 31 and 32 indicate fixed and movable clutch parts of the ratchet type, the former being conveniently fixed to the engine fly wheel 33, and the other splined in the bore of drum 28 and yieldingly held in its normal or projected position by a spring 34. Wound on drum 28 is a line 35, employed for rotating the latter and thereby turning over the crank shaft of the engine. Then the engine starts, spring 30 returns the drum 28 to its normal position, as will be more fully understood in the following. The other end portion of line 35 is fixed to a drum 36 having a pinion with which a toothed segment 37, pivoted on upright 16, meshes. Fixed to and extending upwardly from segment 37 is an arm 38, and into the path of this arm, one end portion of the bell crank lever 39 projects so as to be swung thereby, and this movement of bell crank lever 39 is communicated through a link 40 to switch 26. Shaft 12 is operated through gearing 41 from a shaft 42 driven from the engine shaft 29 by a belt 43 taking over pulleys on the said shafts, as shown. The gear of gearing 41 arranged on shaft 12 is loose and provided with a clutch part adapted for cooperation with a shiftable clutch part 44 splined on shaft 12. Sprocket 15 is fixed to shaft 12, and consequently when clutch part 44 is thrown into engagement with its related fixed clutch part, movement of gearing 41 will be transmitted through sprocket chain 13 to shaft 11 thereby rotating the same to effect the elevation of plunger 3. For shifting clutch part 44 to its open position, I provide a shifting lever 45 which is con nected bya flexible connection 46 with an operating arm 47, fulcrumed on upright 16.

Reference numeral 52 indicates a branch of flexible connection 46 which is connected with switch 26. The actuator 48 for arm 47 is fixed to shaft 11 for rotation therewith, said actuator having an angular free end portion which is adapted to engage arm 47 during lowering of the plunger, and through swinging of said arm effect a draw on flexible connection 46 to swing-shifting lever 45. To close clutch part 44, I provide a shifting lever 49 which is connected by flexible connection 50 with arm 38. An actuator 51, fixed to shaft 11, is provided with an angular extension, adapted to engage arm 38, upon axial shifting of shaft 11, and thereby swinging said arm 38 and segment 37. In this connection, it will be observed that flexible connection 50 normally has sufficient slack so as to permit of segment 37 operating drum 36 prior to the closing of clutch part 44. Therefore engine 24 will be started in advance of the connection of shaft 11 thereto. I have shown shaft 12 provided with a friction disk 55 which is encircled by a brake band 56, having connection with a. suitable operating lever 57, whose free end portion can be engaged with a rack 58, to thereby maintain a braking influence on shaft 12 with a resultant retarding influence on the active movement of plunger 3, should this be desired.

In the modified construction shown in Fig. 7 I have illustrated an electric motor 24, for elevating plunger 3. In the working circuit of this motor, I include the switch 26, which is connected by link 40 with bell crank lever 39. Switch 26 is connected by a flexible connection 52 with operating arm 47. In this construction, bell crank lever 39 is swung by actuator 51 striking arm 38, as plunger 3 approaches the bottom of chamber 1, thereby closing switch 26 so that electrical current will be supplied to motor 24. As plunger 3 moves upwardly, actuator 48 engages arm 47 and opens switch 26. Valves 5 open downwardly automatically during upward movement of plunger and thereby permit of the passage of the fluid through the plunger during its upward or inactive movement.

Various changes can be made in the construction and details thereof, as fall within the scope 'of my invention as defined in the appended claims.

Having thus described my invention what I claim as new, and desire to secure by Let ters Patent of the United States of America, 1s
